【问题描述】：
我正在尝试在 Heroku 上部署一个应用程序，但是当我运行 heroku logs 时，应用程序崩溃了（下面是完整跟踪；下面是 Gemfile 内容）。
You have already activated rack 1.2.1, but your Gemfile requires rack 1.0.1
我正在使用 bundler (1.0.0.rc.6) 进行 gem 管理。
我还有一个 Scrapi 问题，即使 Heroku 在 Linux 环境中运行，它也需要 Mac 库：
Scraper::Reader::HTMLParseError: Unable to load /disk1/home/slugs/254653_91616fb_8a40/mnt/.bundle/gems/ruby/1.8/gems/scrapi-1.2.0/lib/scraper/../tidy/libtidy.dylib

我建议使用 nokogiri，scrapi 看起来很……旧。
